Dam breach reconstruction of the Blažňov pond caused by extreme hydrological event

Publication at Faculty of Science |


This article deals with the reconstruction of the dam breach of the Blažňov pond and consequent flood wave progress in the riverbed of the small brook. Measurements of the wave course and cross sections through valley were made by total geodetic station.

An extraction of flood sediments were carried out at four locations and their textures were analyzed. The reason was a description of the sedimentation process in the reach.

For the modelling of the flood extremity and flood extent the hydrodynamic model HEC-RAS was applied (Hydrologic Engineering Centre - River Analysis System).
